For me nappy hair means "ungroomed" hair no matter the texture, even type 1 hair. I use the term Kinky to describe what's known as nappy hair. Straight, wavy, curly, and kinky describes hair texture. I haven't been called a nappy head before so I can't say how I feel about it(i normally get the good/pretty hair comments). My auntie is relaxed and she will call her hair nappy in a heart beat when she needs a touch up and think nothing else about it lol.
